Benefits of technology

The present invention provides an apparatus and method for effectively receiving a digital broadcasting service with one terminal in an environment where multiple heterogeneous networks coexist. The invention allows a moving terminal that fails to receive a broadcasting service from an existing DMB network to access another heterogeneous network, such as a WiBro network, to seamlessly receive the service. The invention also allows the user to view the broadcasting program content without missing any when the terminal returns back to the DMB network after accessing the WiBro network. Additionally, the invention allows the user to download the missing partial broadcasting program from the WiBro network when the terminal returns back to the DMB network after accessing the WiBro network.

Problems solved by technology

Nevertheless, conventionally, there is no detailed method in which a moving terminal can seamlessly access the heterogeneous networks and communicate with them at a low price when the moving terminal is disconnected from the terrestrial or satellite DMB network as it enters an area where it cannot receive the digital broadcasting service.

Embodiment Construction

[0025]FIGS. 1 through 7, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication system.

[0026]FIG. 1 illustrates a radio access environment where various communication networks coexist. As shown in the drawing, a terminal (or mobile station) 101 can access not only the DMB network but also the 3G cellular network, the WiBro network (or Wireless Metropolitan Area Network (WMAN)) network and the WLAN network. The terminal 101, although it can access several communication networks, generally accesses the DMB system most suitable to provide free or low-priced broadcasting services, and receives therefrom various content, such as sports, movies, television sho...

Abstract

A method for providing a Digital Multimedia Broadcasting (DMB) service to a terminal communicable with different communication networks. The DMB service method includes receiving a broadcasting program over a DMB network; receiving the broadcasting program over a Wireless Broadband (WiBro) network upon failure to receive the broadcasting program signal from the DMB network; and upon receipt of the broadcasting program signal back from the DMB network, interrupting the broadcasting program received from the WiBro network and receiving the broadcasting program over the DMB network.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY[0001]The present application claims the benefit under 35 U.S.C. §119(a) of a Korean Patent Application filed in the Korean Intellectual Property Office on Nov. 9, 2006 and assigned Serial No. 2006-110510, the disclosure of which is incorporated herein by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates generally to broadcasting services, and in particular, to an apparatus and method for providing seamless digital broadcasting services economical for the user by interworking between heterogeneous networks.BACKGROUND OF THE INVENTION[0003]Digital broadcasting refers to the broadcasting service that provides users with high-definition, high-fidelity and high-quality broadcastings, in replacement of the conventional analog broadcasting. With the recent development of the digital broadcasting and mobile communication technologies, there is an increasing interest in the study for allowing the user...
